Although the research was conducted on an Apple Watch, Johnson Hsieh, Cardiogram’s co-founder, told TechCrunch that similar devices such as Fitbit would work in the same way so long as they have a heart monitor.

‘The idea here is that by screening continuously you would identify people with hypertension who might not know they have it.’.

‘And then you’d guide them through the appropriate final diagnosis, which would be through a blood pressure cuff and then treatment,’ said Hsieh.
